I had just imported all the data to my report. I had one excess tab, which i decided to remove. It was the only tab on the report at the moment, but i figured it would just delete it and create a new empty one.
After a while of processing and nothing had happened, i decided to save my progress and open the report again.
"Unexpected Error. Failed to load the report" text greeted me when i opened the file again.
"An error occured while rendering the report" message popped up when i tried to insert any graphs on the report, it also reappears instantly when i press cancel.
New page button on the bottom left corner doesn't respond.
All data and tables are there untouched, i just can't make any graphs with them.
Version i'm using: 2.63.3272.40461 64-bit (October 2018)
